Target Disk Mode Not Working on Your Mac? Here’s How to Fix It

Are you experiencing issues with target disk mode on your Mac? Target disk mode is a handy feature that allows you to access the hard drive of another Mac and transfer files between them using a FireWire or Thunderbolt cable. However, if you’re facing problems with this feature, don’t panic. In this comprehensive guide, we’ll walk you through some common solutions to fix target disk mode not working on your Mac.

Detailed Discussion on Target Disk Mode Not Working on Your Mac

Here are some common solutions to try if your Mac’s target disk mode is not working:

1. Check Compatibility

The first step is to ensure that your Mac supports target disk mode. Older Macs without Thunderbolt ports will not support target disk mode over Thunderbolt cables. However, FireWire-based target disk mode is supported on older Macs with FireWire ports, whereas newer Macs have switched to Thunderbolt.

2. Check Connection and Cable

If your Mac supports target disk mode, check the connection and cable. Ensure that the cable is not damaged and is securely plugged in on both Macs. Additionally, try using a different cable to rule out any cable-related issues.

3. Check Disk Utility

Open “Disk Utility” on the Mac that’s not working and select the primary hard drive. Click on the “First Aid” button to check for errors and repair any issues.

4. Try Safe Mode

In some instances, the Mac’s target disk mode may not work because of conflicting apps or settings. Running the Mac in Safe Mode can rule out such issues. To boot into Safe Mode, press and hold the Shift key while turning on the Mac.

5. Reset SMC and PRAM

If the above-mentioned solutions don’t work, resetting the System Management Controller (SMC) and Parameter RAM (PRAM) can help. Here’s what you need to do:

For SMC –
– Shut down the Mac and connect it to a power source
– Press and hold the Shift + Control + Option keys along with the Power button simultaneously
– Release all keys and turn the Mac on again

For PRAM –
– Shut down the Mac and wait for a few seconds
– Press the Power button and immediately press and hold Option + Command + P + R keys
– Release all keys and wait for the Mac to restart
